Controlled-release fertilizers used to feel like a niche, premium add-on, the kind of thing you only saw in a few high-value crops. Now they’re starting to look like a practical answer to a problem most growers wrestle with all the time: how do you grow more while losing fewer nutrients along the way?
And that problem isn’t abstract. FAO’s fertilizer statistics show global agricultural use of inorganic fertilizers rising from 142 million tonnes in 2002 to 190 million tonnes in 2023, made up of about 112 million tonnes of nitrogen, 41 million tonnes of phosphorus, and 38 million tonnes of potassium. Our World in Data’s FAO-based fertilizer consumption dataset, updated in February 2026, tracks the same long-run climb through 2023.
At the same time, price volatility and supply swings have made efficiency feel less like a nice-to-have and more like the point. FAO reported in late 2025 that fertilizer production rebounded in 2024 and 2025, led by nitrogen and potassium, and that the average price of a stylized fertilizer basket hit USD 489 per tonne in September 2025. That was still below the record highs of 2022, but it stayed high enough that timing, losses, and product selection kept showing up in budget conversations.
This is where controlled-release fertilizer, usually shortened to CRFs, starts to matter strategically. Instead of dumping nutrients into the soil all at once, CRF products are designed to release them over time, ideally closer to when the crop needs them. In real-world terms, that may translate into fewer passes, less leaching risk, steadier growth, and a better return on every tonne you buy.
This article takes a fairly practical look at five names that come up a lot in CRF conversations: ICL Group, Nutrien, Haifa Group, COMPO Expert, and Yara International. I’m not trying to crown one universal winner, because there probably isn’t one. The “best” supplier depends on the crop, region, labor and equipment realities, irrigation setup, and how hard sustainability requirements are pushing on your program.
The goal is simpler, help technical buyers and agronomy teams see where each company seems to put its CRF emphasis publicly, and how to think through choosing a partner without getting distracted by branding.
What Is Controlled Release Fertilizer
Controlled-release fertilizer is engineered to release nutrients gradually instead of all at once. Most CRF products look like ordinary granules, but each granule has a semi-permeable coating. Water moves in, dissolves the nutrient core, and nutrients then diffuse outward over time into the root zone. When it works as intended, you get a steadier nutrient supply that can match crop uptake more closely.
That sounds straightforward, but it addresses several expensive headaches. Conventional fertilizers can do the job, but they often release nutrients faster than plants can take them up. When the crop can’t keep up, nutrients can be lost through leaching, runoff, volatilization, denitrification, or fixation in the soil. CRF technology is designed to slow the release so losses are less likely, which is why it keeps getting tied to nutrient use efficiency and environmental performance.
It also helps to separate controlled-release from slow-release, because people mix them up. In a lot of manufacturer materials, controlled-release usually means coated products with more predictable release patterns, often driven mainly by temperature and coating design. Slow-release products are often described as more dependent on water availability, pH, and microbial activity. That distinction matters because buyers who pay for CRFs are often paying for predictability as much as they’re paying for NPK.
Practically speaking, CRFs tend to be most attractive where nutrient losses are costly or where in-season applications are a pain, or both. Think light soils, rainy regions, orchards, nurseries, greenhouses, turf, forestry, and field systems where split applications are labor-intensive or weather-risky. It can also be appealing where nitrogen loss regulations are tighter, or where the operation wants a simpler program with fewer trips across the field.
How Controlled Release Technology Works
The basic idea behind CRFs is simple: control the release with a coating. The granule has a nutrient core and a coating made from polymer, resin, sulfur-based systems, or other proprietary materials. Once the granule sits in moist soil, water penetrates the coating, the core dissolves, and the dissolved nutrients diffuse outward through the coating over time.
Where things start to diverge is in the coating sophistication and how consistently it performs. ICL describes E-Max as a polymer-coated technology focused on improving nutrient use efficiency, with release influenced by temperature and moisture, and with longevities that range from short programs up to 16 to 18 months in some product lines.
COMPO Expert describes an elastic polymer coating with Climate Adapted Release technology, positioned around consistent supply for up to 16 months. Haifa’s Multicote Agri portfolio is offered in multiple release profiles, including 4-, 6-, and 8-month formulas.
That release control has real agronomic benefits. If the release curve matches the crop’s demand reasonably well, growers can sometimes replace multiple split applications with one early application. That can reduce labor, simplify logistics, and lower the odds of swinging between deficiency and oversupply during sensitive growth stages. Not surprisingly, that’s exactly how most manufacturers frame the value.
The useful way to think about CRFs is as a nutrient delivery system, not a miracle product. The coating can matter just as much as the nutrient analysis on the label. Two products can show similar NPK percentages and behave very differently in the field because their release timing, coating integrity, and crop fit aren’t the same. That’s why comparing CRF manufacturers usually requires looking past nutrient numbers and into how they design, explain, and support release behavior.
Leading CRF Manufacturers
These five companies all show up in controlled-release or controlled nutrient delivery discussions, but they don’t all play the same role. Some look like true CRF specialists. Some look more like broad crop nutrition companies with a specific controlled-release angle. And the “best fit” shifts a lot depending on whether you’re managing orchards, nurseries, turf, greenhouse crops, or broadacre row crops.
ICL Group
ICL Group looks like one of the most clearly dedicated CRF players here, with a broad platform centered on E-Max and multiple product lines such as Agroblen, Agromaster, and Agrocote. The public positioning leans heavily into one-time application, predictable longevity, and reduced leaching risk, with release windows ranging from a few months up to about 16 to 18 months in some lines. This tends to suit buyers who want a CRF-first supplier across several crop systems, field crops, horticulture, plantations, and high-efficiency programs.
Nutrients
Nutrien’s controlled-release offering is most commonly associated with ESN, a polymer-coated nitrogen fertilizer designed to reduce nitrogen losses while maintaining crop yield potential. The technology is positioned around protecting nitrogen investment by limiting losses from leaching, denitrification, and volatilization. It is most often used in field crops where nitrogen efficiency is a major agronomic and economic concern.
Haifa Group
Haifa’s controlled-release portfolio centers on Multicote Agri and related polymer-coated fertilizers designed to deliver nutrients gradually throughout the growing season. These products are commonly used in situations where nutrient losses are a concern, such as light soils, high rainfall environments, or crops with high nutritional demand. They are often applied in orchards, horticulture, and other high-value cropping systems where consistent nutrient availability and reduced application frequency are important.
COMPO Expert
COMPO Expert is widely recognized in horticulture and specialty crop systems, with coated fertilizers such as Basacote and other controlled-release products designed to provide consistent nutrient supply over extended periods. These technologies focus on coating integrity and controlled nutrient release to support steady plant growth throughout the production cycle. They are commonly used in nurseries, landscaping, ornamentals, and other substrate-based intensive systems where predictable nutrient availability is critical.
Yara International
Yara is one of the world’s largest crop-nutrition companies, with a global portfolio that includes nitrogen fertilizers, complex NPK products, and specialty crop-nutrition solutions. While the company is not primarily known for a dedicated controlled-release fertilizer platform, it plays a major role in global crop nutrition through its agronomic advisory services, specialty nutrition products, and digital decision-support tools. For many buyers, the value lies in combining conventional fertilizers with targeted crop-nutrition programs supported by a large technical network.

Benefits for Nutrient Efficiency
CRFs start to look more compelling when you zoom out and remember the scale. With global inorganic fertilizer use at 190 million tonnes in a single year, small changes in nutrient capture can add up to big agronomic and environmental impacts.
- Better synchronization with crop demand is the first and most obvious benefit. If nutrients become available gradually, plants have a better chance of absorbing them before the system loses them. That’s the core promise behind nearly every CRF, whether it’s framed as nitrogen protection, multi-nutrient feeding, or season-long consistency.
- Lower nutrient loss risk is the second benefit, and it’s both environmental and financial. Nutrient losses can show up as water quality issues or emissions issues, but they also show up as wasted spend. When fertilizer prices stay elevated, even if they’re off the 2022 peak, the economics of reducing losses become a lot easier to defend in a procurement meeting.
- Operational simplicity comes next. Many CRF programs are sold on the idea that one pre-plant or early-season application can replace several split applications. That’s valuable where labor is expensive, machinery passes are limited, weather windows are narrow, irrigation timing is complex, or crop canopy makes mid-season access difficult. Orchards and horticulture are the classic examples, but broadacre operations run into the same “we just can’t get back in there” problem more often than people admit.
- More uniform crop performance is another commonly cited benefit. A steadier nutrient supply can reduce the boom-and-bust feeding pattern and support more even growth. Manufacturers talk about yield and quality, of course, but even from a buyer’s perspective, uniformity has practical value; it affects pack-out, harvest timing, marketable output, and how predictable the whole crop program feels season to season.

Choosing the Right CRF Supplier
The best CRF supplier usually isn’t the biggest brand on paper. It’s the one whose product behavior, technical support, and supply reliability fit the system you actually run. If you want a quick reality check before you buy, five questions tend to separate a smart CRF decision from an expensive mismatch.
- How predictable is the release profile?
A CRF product is only as good as its consistency. Look for whether the supplier can explain what drives release, how it defines longevity, and how the coating behaves under real field conditions. If a company can clearly connect coating design to release behavior, that usually suggests the program is more than marketing.
- Is the portfolio built for your crop and production model?
A supplier that shines in nursery substrates may not be your best option for broadacre nitrogen management. The reverse is also true. Crop-system fit tends to beat general brand familiarity, especially when you’re paying for controlled behavior.
- Does the company offer enough formulations and longevities?
Portfolio depth matters because it gives you room to match products to crop stage, soil type, climate, and labor model. Dedicated CRF specialists often have an advantage here simply because they’ve invested more heavily in tailoring.
- How strong is the agronomic support?
CRFs are rarely just a bag choice; it’s a program choice. The best suppliers help with rate setting, timing, crop matching, and integration with the rest of the nutrition plan. This matters even more if you’re switching from soluble or conventional granular approaches and you’re still learning how release curves behave in your conditions.
- How credible is the efficiency and sustainability story?
Public claims should line up with actual technology and real use cases. I’d be cautious of vague sustainability language that never really explains the mechanism. Clear technical explanations, even if they come with caveats, tend to be more trustworthy.
Applied to the five companies discussed here, the fit differences are fairly distinct. ICL Group looks like a strong option when a buyer wants a broad CRF specialist with multiple product families and clear positioning around controlled release.
Nutrien stands out when nitrogen efficiency in field crops is the primary driver.
Haifa Group looks particularly compelling for intensive horticulture, orchards, and situations where timing and access make mid-season application unrealistic.
COMPO Expert looks well suited to horticulture-oriented systems that need long, consistent feeding.
Yara International looks attractive when the buyer prioritizes global scale, agronomic infrastructure, and integrated nutrition support, even if CRF is not the most visible part of its public portfolio.
Conclusion
Controlled-release fertilizers aren’t just a premium input for a narrow set of crops anymore. It’s increasingly a strategic tool for managing cost, efficiency, labor constraints, and environmental pressure in modern agriculture. With global fertilizer use still high and markets still sensitive to supply shifts and affordability, technologies that improve nutrient timing have become easier to justify, both agronomically and commercially.
Across the companies reviewed here, ICL Group and Haifa Group come across as the clearest CRF specialists in public positioning, Nutrien stands out for controlled-release nitrogen, COMPO Expert looks especially strong in horticulture-oriented coated nutrition, and Yara International brings the advantages of scale and integrated crop nutrition. None of that makes a single universal winner. It just means the “right” choice depends on whether you care most about nitrogen protection, high-value horticulture performance, broad portfolio depth, long-season feeding consistency, or a globally supported nutrition program.
